* Use 16-bit audio output
* More audio tweaks (mute on startup, working volume control)
* Treat the rotary input as a scroll wheel (works now)
To-dos:
* Better global keymap (incorporate touchscreen)
* Turn on plugins and define the approximately eight bajillion keymaps
* Still have some audible pops when we turn on, need to figure out why
* Default Cabbiev2 comes off as rather crappy on this device
...I don't know how much work I will do on this thing, as the limited
number of physical controls (and a lack of a line-out) mean I'd never
want to use this thing myself.
